For example, both of the display 410 andthe terminal device 420 may be provided with the configurationcorresponding to the controller 47.

FIG. 7 is a diagram illustrating an example of an operation of thedisplay controller 472 of the user interface device 40. The displaycontroller 472 determines whether a preset display stop condition issatisfied (Step S101). The display stop condition is a conditionindicating a likelihood that a difference occurs between informationstored that is in the provision information memory 121 of the server 10and information that is stored in the provision information memory 461of the user interface device 40. If the display stop condition issatisfied, it can be presumed that provision information that is storedin the provision information memory 461 is old information. The displaystop condition may be such a condition that the communication via thecommunicator 41 has not been normally executed, for example. Morespecifically, it may be a condition that a state where the controller 47is unable to acquire communication data from the communicator 41 hasbeen continued over a prescribed period. The display stop condition maybe such a condition that a trouble occurs in a communication path withthe server 10, for example. More specifically, it may be a conditionthat data (data for survival confirmation) that needs to be receivedfrom the server 10 at a prescribed timing has not been normallyreceived. The display stop condition may be such a condition that thecontroller 47 is unable to acquire new provision information over aprescribed period, for example. The display stop condition may be such acondition that the facility user P related to the provision informationis proceeding a hospital discharge procedure, for example. Morespecifically, the display stop condition may be a condition that statusinformation that is registered with electronic medical record data ofthe facility user P related to the provision information is during thehospital discharge procedure. When the hospital discharge procedure isproceeding, the facility user P to whom the user interface device 40 isallocated is generally changed before and after the hospital dischargeprocedure, so that there is a possibility that the facility user P isnot correctly allocated. Such a condition is set as a display stopcondition to make it possible to prevent information related to thefacility user P during the hospital discharge procedure from erroneouslydisplaying on the user interface device 40.

If the display stop condition is not satisfied (Step S101—NO), thedisplay controller 472 continues display on the display 43. In thiscase, the display controller 472 causes the display 43 to display a partor all of the content of the provision information, for example. On theother hand, if the display stop condition is satisfied (Step S101—YES),the display controller 472 stops display of the provision information onthe display 43 (Step S102). In this process, the display controller 472stops display of information related to at least biological informationon the facility user P, among the provision information on the display43. When the display controller 472 stops the display, an image orcharacters indicating that the display is sopped is displayed on thedisplay 43. Such an image or characters may be displayed under thecontrol by the display controller 472, or may be displayed under thecontrol by the display 43. For example, the display controller 472 maygenerate a video signal indicating the abovementioned image orcharacters, and may output the video signal to the display 43. Forexample, the display 43 may display the abovementioned image orcharacters in response that the display controller 472 stops the outputof the video signal to the display 43. When the display is stopped,neither of an image nor characters may be displayed on the display 43.The display controller 472 may be configured not to display informationrelated to the facility user P with which the user interface device 40is associated, when the display is stopped.

After stopping the display, the display controller 472 determineswhether a display resume condition is satisfied (Step S103). The displayresume condition is a condition indicating that the provisioninformation that is stored in the provision information memory 461 hasbeen updated to the latest information. If the display resume conditionis satisfied, it can be presumed that the provision information that isstored in the provision information memory 461 has been updated to thelatest information. The display resume condition may be such a conditionthat the normal execution of the communication via the communicator 41has become possible, for example. More specifically, it may be such acondition that the controller 47 has become possible to acquirecommunication data from the communicator 41. The display resumecondition may be such a condition that the trouble having occurred inthe communication path with the server 10 has recovered, for example.More specifically, it may be a condition that data (data for survivalconfirmation) that needs to be received from the server 10 at aprescribed timing has been normally received. The display resumecondition may be such a condition that the controller 47 has becomepossible to acquire new provision information, for example. The displayresume condition may be such a condition that an operator having aprescribed authority has input an instruction to resume display with theuser interface device 42. The controller 47 may determine whether theprescribed authority is present on the basis of the authenticationinformation received via the wireless communicator 44, for example. Theoperator having a prescribed authority is, for example, among thestaffs, a person (for example, a doctor in charge, a doctor attending,or a nurse in charge) in charge of medical treatment or care for thefacility user P to whom the user interface device 40 is allocated.

If the display resume condition is not satisfied (Step S103—NO), thedisplay controller 472 remains the display on the display 43 stopped. Onthe other hand, if the display resume condition is satisfied (StepS103—YES), the display controller 472 resumes the display on the display43 (Step S104). When the display controller 472 resumes display, ascreen that is displayed in normal times is displayed on the display 43.For example, the screen having been displayed before the display isstopped at Step S102 may be displayed on the display 43. In this case,newly acquired provision information may be displayed in a region wherethe provision information is displayed within the displayed screen.

In the information providing system 1 configured in this manner in thefirst embodiment, it is possible to suppress unsuitable information fromproviding to a person who undergoes medical treatment or care (thefacility user P). The following describes in details.

In the information providing system 1 in the first embodiment, when acondition indicating (display stop condition) that a difference occursbetween provision information stored in the server 10 and provisioninformation stored in the user interface device 40 is satisfied, thedisplay on the display 43 is stopped. In such a case, it isinappropriate to provide the provision information that is stored in theuser interface device 40 to the facility user P because there is apossibility that the provision information stored in the user interfacedevice 40 may include an error content. The display controller 472 ofthe user interface device 40 operates in the abovementioned manner, sothat it is possible to suppress the provision information having apossibility of being old from being provided to the facility user P.

In the information providing system 1 in the first embodiment, when acondition (display resume condition) indicating that the provisioninformation is updated to the latest information is satisfied after thedisplay stop condition is satisfied and the display is stopped, thedisplay on the display 43 is resumed. This makes it possible to rapidlyprovide the updated latest provision information to the facility user P.

The server 10 may be mounted on a plurality of devices by the functionthereof being separated thereto. For example, the electronic medicalrecord data memory 123 and the electronic medical record controller 133may be mounted to another device as an electronic medical record server.

Although the configuration in which the user interface device 40 isinstalled in a room where the facility user P stays or lives and oneuser interface device 40 is associated with one facility user P isdescribed in the present embodiment, one user interface device 40 may becommonly used by a plurality of the facility users P or may be installedin a path such as a corridor.

The output device 45 may be provided with an output device having a modedifferent from the speaker 451 and the lighting device 452. For example,the information providing system 1 may be provided with an output devicethat makes a notification by generating vibration, or may be providedwith an output device that makes a notification by moving a movablepart. The output device 45 is not necessarily provided with both of thespeaker 451 and the lighting device 452.

In a case of a display stop state (state where the display stopcondition is satisfied), the display controller 472 may displayprescribed information if a prescribed condition is satisfied. Forexample, when the staff logs in the user interface device 40 (prescribedcondition), the display controller 472 may display information on thefacility user P (for example, patient) with which the user interfacedevice 40 is associated. In this case, the display controller 472 maydisplay information in a mode indicating that there is a possibilitythat the displayed information is old. Specific examples of such displaymodes include a mode of displaying information by changing thebackground color, a mode of displaying characters or an image(pictogram) indicating the display stop state, and a mode of displayingthe time when the information being displayed is acquired for the lasttime or the time when the information being displayed is updated for thelast time.

The display stop condition may be defined as a condition indicating alikelihood that a difference occurs between a state indicated by theinformation that is stored in the memory 12 and an actual state relatedto medical treatment or care. For example, such a case may occur that inthe facility user information memory 122 of the memory 12, whenidentification information on a facility user called “A” is registered,the facility user called “A” is no longer a facility user due tocircumstances such as a hospital discharge. In such a case, even when nodifference occurs between information that is stored in the server 10and information that is stored in the memory 12, it may be determinedthat the display stop condition is satisfied. Such a determination maybe made, for example, based on whether a staff in charge of the hospitaldischarge procedure has performed a prescribed operation with respect tothe user interface device 42 of the user interface device 40 related toa facility user who is going to leave the hospital or has already leftthe hospital. The prescribed operation may include a button indicatingthe hospital discharge being pressed, for example.

When communication with the relay information equipment via the wirelesscommunicator 24 becomes possible, regardless of an operation by thestaff, the determining unit 272 may transmit provision information tothe relay information equipment. With such a configuration, provisioninformation is automatically transmitted to the relay informationequipment staff without the specific awareness of the staff.

The determining unit 272 may transmit only provision information thatneeds to be transmitted to the relay destination terminal, to the relayinformation equipment. The provision information that needs to betransmitted to the relay destination terminal is provision informationto be provided to the facility user P to whom the relay destinationterminal (the user interface device 40 a) is allocated.

The function of the determining unit 272 may be provided not to themaster station device 20 a but to the server 10. In this case, with thefunction of the determining unit 272, the provision information istransmitted to the terminal device 30 a not via the wirelesscommunicator but via the communicator 11. The acquisition unit 371 ofthe terminal device 30 a receives provision information via thecommunicator 31 from the server 10.

The information relay unit 372 may transmit provision information storedin the provision information memory 361 to all the user interfacedevices 40 a that become communicable via the wireless communicator 34.
